ZENIT St Petersburg boss Roberto Mancini will see a “much different” Scott Sinclair when their paths meet again on Thursday night, according to the Celtic winger.

The 28-year-old was signed by Manchester City in 2012 from Swansea when Mancini was in charge at the Etihad Stadium, but he failed to make an impact under the Italian, joining Aston Villa in 2015 after loan spells at West Brom and Villa, before arriving at Parkhead a year later.

Sinclair has become a mainstay of Brendan Rodgers’ side since then, winning a domestic treble in his first season and looking for a second this year, and is currently the Hoops top scorer with 17 goals.

‘We know where we stand’: Brendan Rodgers says Celtic are underdogs against Zenit St Petersburg

Ahead of the first leg of their Europa League clash with Zenit at Celtic Park, the Englishman recalled his time under the Italian and said: “When I went to City I only played a few games under him. I am much different.

“But there are so many players there that didn’t really get as much game time as they would have liked.

“I am a much more different now, than then.

“I don’t have a point to prove to him, it’s for myself.

“You have these targets and the levels that you want to play at and for me it is working hard and giving it 100 per cent.

“He is a very tactical manager, I am sure he will be doing a lot of tactical work to stop us performing tomorrow and I am sure he will be wanting to win the game.”
